REGULATOR FOR GAS-LAMPS.

Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed September 6, 1904. Serial No. 223,398.

To all whom it may concern:

Be it known that we, OLE MIKAEL J OHAN OLsEN, builder, and WALTER GATES,grocer, citizens of the Commonwealth of Australia, residing at Churchstreet, Parramatta, in the State of New South Wales, Commonwealth ofAustralia, have invented certain new and useful Improvements inRegulators for Gas- Lamps; and we do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention consists of a novel mechanical appliance the workingparts of which are adapted to be wholly inclosed within a gaschamberused as a regulator, so that the working parts, which are operated bysuch regulator, may be protected by it from possible disarrangement. Themechanism forms a simple and effective controlling device for directingthe flow of gas alternately through dual passages, so as to obtain theseparate ignition of associated burners (designated a pilot-light andburner) and also to secure their separate extinction and subsequentrelighting as frequently as may be desired.

A peculiarity of the invention is that while it may be operated by anypredetermined maximum gas-pressure it is not subject to the influence ofintermediate or varying pressures by reason of a device suitablyarranged for temporarily suspending the alternating action, suchtemporary suspension continuing for any period determined bytheoperator.

A mercurial or glycerin governor with a bell and central stem modifiedaccording to this invention (and influenced in the usual way bygas-pressure) is a type of chamber suitable for inclosing the mechanism,whose associated parts are so arranged as to produce, with reliable andunerring accuracy, the requisite alternate controlling and relievingmovements.

Referring to the accompanying drawings, which form part of thisspecification, Figure 1 shows, partly in elevation and section, theinclosing chamber and regulator with the operative parts thereinadjusted in their normal position to communicate with the pilotlight andready to be operated. similar elevation and section to Fig. 1', butshowing the altered position of theparts when pivots for preventingproducing ignition of the'main burner and extinction of the pilot-light.Fig. 3 is a similar view to Figs. 1 and 2, showing the position of theparts during the temporary suspension of the alternating action. Fig. Ais a view of the under side of the chamber, showing method of clampingemployed. Fig. 5 is a plan or top view of the. chamber with bellremoved, showing the parts as seen in Fig. 1. Fig. 6 is an enlargeddetail of the pendulum and looped link, as in Fig. 1. Fig. 7 is asimilar enlarged detail to Fig. 6, but showing the pendulum and loopedlink in their relative positions for producing the releasing movement.Fig. 8 is an enlarged detail of a form of bypass chamberadapted for usewith this invention for extinguishing and relighting incandescentburners.

The chamber A has the concentric container B for holding the gasintercepting and buoyant medium, which may be mercury,

Vaseline, or the like and maybe constructed of glass or other suitablematerial. The bell or dome C is fitted to move freely in the aforesaidconcentric container B and carries the adjustable central stem D,hereinafter re ferred to. The cover E renders the chamber dust-proof. Anopening is provided in the bottom of the chamber A for the passage ofthe projecting parts associated with the foundation-plate F. These partsconsist of the central gas-union G, which is the main supply-pipe andwhose clamping-nut H secures the clamping-plate I, (see Fig. 4,) thepilot outlet-tube J communicating with the side tube K and the burneroutlet-tube L communicating with its side tube M. Each of the saidoutlet-tubes are projected upwardly into their respectivemercury-chambers N and O and are covered by the bells P and Q, suspendedfrom the balance-lever R, supported upon the standard S of thefoundation-plate F, one side of which standard is not shown upon thevarious figures for the purpose of more clearly disclosing the operativeparts.

The long side standard T carries the upper and lower parallel bars Uand. V, whose opposite ends are attached to the central stem 1) of thebell C and are arranged to secure the vertical movement of the saidstem. These levers are provided with slots U V to allow a certain amountof longitudinal play on their lost motion and bind.-

sition and the ing. The shorter side standard W carries the lever X,having the weighted arm D to counteract the pressure of the buoyantmedium and joined at its opposite end by the connection Y to theparallel bar V and is operated thereby. The independent lever Z issecured above the bar V to the same stand ard and is provided with thecam-shaped end A. It is arranged for connection with the connection Y,so that during the upward movement of the stem D it Will be caused torise and engage with the looped lever B, suspended from the pin whichsupports the balance-lever R. The said balance-lever depends for itsmovement upon the independent lever Z, to which it is attached by theconnecting-rod C. It should be here explained that the whole of theselevers are compounded to admit of their operation on either side of thecontainers N and 0.

In Fig. 1 the mechanism is shown with the operative parts in theirnormal position to allow the gas which has entered into the chamber Athrough the supply-pipe G to pass into the chamber N and out through thepilot outlet-tube J, communicating with the side tube K, and thence tothe by-pass chamber G, having the division H for separating it fromchamber I, which communicates with the burner. In this figure the bellor dome O is in its lowermost position. In Fig. 2 the bell C has beenraised to its highest poassociated operative parts have changed to theposition shown. During the rising movement of the independent lever Zthe balance-lever R has been canted, by means of the connecting-rod C,in the opposite direction to that shown in Fig. 1, thus closing thepilot pipe J and opening the burner outlet-tube L, communicating withthe side tube M, associated with the chamber I of the burner. The bellsP and Q are so arranged in the relative lengths of their suspending rodsthat the complete cutting off of the gas from their respective chambersshall not be accomplished until ignition takes place either with theburner or the pilot-light. In Fig. 2 it is to be observed that thecrosshead J has pushed the pendulum E (see also Fig. 6) away from thestop F of the loop-lever B, which will allow the independent lever Z tobecome engaged in the manner shown, as also in Fig. 3, this lever beingthen in contact with lower bar V. Results shown in Fig. 2 are to beobtained with any desired pressure of gas to which the apparatus can beadjusted. In Fig. 3 the mechanism is shown in a position consequent upona reduction of pressure. The dome O has descended, and with it theparallel bars U and V, also the lever X, with its connection Y, at

tached to the cross-head J stem D. The pendulum E has swung out of thecenter in the opposite direction to that shown in Figs. 1 and 2, so thatif the dome C of the central ert a pressure on the side of the pendulumnearest to it, and by forcing it against the stop F of the looped leverB (see Fig. 7) would cause it to release lever Z, which would then fallback into the position shown in Fig. 1 and the burner would beextinguished, but the pilot-light would be prepared for relighting itwhen the dome C was again operated. It is to be understood that therelease of lever Z cannot be obtained by the varying gaspressuresranging between the minimum and maximum.

Having now described our invention, what we claim as new, and desire tosecure by Let ters Patent, is I 1.
